6.3 EMC test operation „RUN Mode“
Before you start an EMC test, you should be familiar with the following:
„Run Mode“ is defined as an EMC test operation such as EFT, ESD etc. The „Run Mode“ is indicated by
the blinking LED on the operation panel of the front. Pressing the RUN-button sets the TRA3000 F-S-D-V-C
into the RUN mode. During RUN Mode, the corresponding test-LED on the operation part blinks and the
corresponding coupling path is illuminated.
Renewed pressing of the RUN-button stops the generator (Reset to the standby mode).
In
„Standby Mode“ the power to the TRANSIENT is switched on. The control is activated. No high voltage
source is switched on.
Depending on local safety standards, an emergency stop must be installed. All operators and laboratory
personnel must be able to reach the emergency stop. On the rear side of the TRA3000 F-S-D-V-C there is
an
EMERGENCY STOP input. See Chapter 5 „Preparation for Operation“.
Trigger
.
After the RUN button has been pressed, the tester is started, but not the EMC test. As soon the generator
is ready ( e. g., the impulse capacitor is charged), the LED on the trigger button is illuminated. As soon as
the LED is illuminated a single EMC test can be initiated (Burst, ESD, DIP, Variation). The next trigger can
take place when the LED is illuminated again.
During ESD, the trigger button has the same function as the button on the ESD discharge network.
6.3.1.1 Changing values during operation
In RUN-mode, most of the parameters can be continuously varied using the „+“ and „- “ buttons. This is
very helpful for exactly determining of the immunity level of the EUT. The manual change of the nominal
voltage will be noted in the report with a warning.
If ramp has been chosen, the different values will change as follows:
Voltage ramp V-peak V
Frequency ramp Freq. kHz
Burst duration Burst Dur
Synchronisation Synchro °
For very fast investigation the coupling paths can also be changed during operation by pressing
the N, PE, L buttons.
